Kai's verdictA-tier. Best for teaching a kid to code in 2026.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
